Aircraft lavatory

Abstract

A lavatory complex for an aircraft. The lavatory complex includes a male lavatory facility and a female lavatory facility. The male lavatory facility includes stall units and may include urinals. The female lavatory facility includes stall units. Each stall unit suitably includes a single commode. The male and female lavatory facilities include at least one sink separated from the stall units by stall unit doors. The lavatory complex may include sinks that are not located within either the male or female lavatory facilities. A lavatory may include illuminating indicators; an illuminated, folding, baby changing station; a vanity; a self-cleaning toilet; and / or an illuminated faucet.

Description

PRIORITY CLAIM[0001]This application claims the benefit of U.S. Provisonal Ser. No. 60 / 449,967, filed Feb. 25, 2003, which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates generally to aircraft and, more specifically, to aircraft lavatories.BACKGROUND OF THE INVENTION[0003]Current airplane lavatories are typically single, small units that include a commode and a sink. For example, the current aft end of the BOEING 777 commercial airplane, as shown in FIG. 1, includes a group of 6 individual lavatories. These six lavatories serve approximately 200 people. Therefore, each lavatory must serve approximately 34 people. When a passenger uses the lavatory unit, all the amenities of the unit are unavailable for use by another passenger—even when the passenger only occupies the unit to just use the sink. This can result in long lines of people waiting in the aisle for an available lavatory.[0004]In order to reduce waiting times for aircraft lavatories, i...

AI Technical Summary

Benefits of technology

[0008]The present invention provides separate male and female lavatory complexes that allow for efficient use of fixtures, thereby allowing more passengers to cycle through while providing a more comfortable atmosphere for the passengers.

[0015]In another aspect of the invention, a vanity mirror with adjustable lighting creates appropriate lighting for different skin tones.

[0016]In still another aspect of the invention, the present invention provides efficient use of space with a small footprint for maximizing seat space and efficient use of services / amenities. The present invention is also more accessible with more user friendly devices, such as indicator lights. The lavatories suitably are modular units that have self-contained plumbing and wiring for connection to airplane systems at an interface.

[0017]Services are available from the exterior of the lavatory to increase the user / unit ratio. Thus for the same space, more passengers are served, and each passenger may be served quicker.

Problems solved by technology

When a passenger uses the lavatory unit, all the amenities of the unit are unavailable for use by another passenger—even when the passenger only occupies the unit to just use the sink.

This can result in long lines of people waiting in the aisle for an available lavatory.

However, installing more lavatories also reduces the available space for passenger seats.

This results in a decrease in the ability of such an aircraft to generate revenue for an airline.

However, there is an unmet need to improve the efficiency of aircraft lavatories.

Further, airlines have indicated that passengers often have difficulty locating necessities in the lavatory.

For example, passengers may not be sure where to find paper towels, how to get to the trashcan, or how to flush the toilet.

This can lead to frustrated passengers and dirty facilities.

Traditionally, items in the lavatory have been stored in discrete locations, which can cause them to be difficult for passengers to find.

Placards are often included in lavatories, but placards can result in too many words to focus on or confusing symbols the passenger may not understand.

Placards may also be subject to vandalization.

Therefore, there is an unmet need to improve instructions for using an aircraft lavatory.
